摘要/Abstract

摘要： 本研究探讨应用锥形束CT(CBCT)观察即刻种植后牙槽骨吸收及种植体稳定情况。选取在我院行种植修复患者200例,共植入种植体330枚。采用CBCT测量即刻种植的牙槽骨吸收量和种植区颌骨亨氏单位(HU)值,采用Qstell ISQ种植体稳定性测量仪测量种植体稳定系数(ISQ)值。结果显示,术后1年,下颌前牙、下颌后牙牙槽骨吸收量明显少于上颌前牙、上颌后牙(P<0.05);术后1年,上颌前牙、上颌后牙、下颌前牙、下颌后牙红色美学评分(PES评分)比较差异无统计学意义(P>0.05);下颌前牙、下颌后牙颌骨HU值,ISQ值明显高于上颌前牙、上颌后牙(P<0.05);直径4.3 mm和5.0 mm种植体ISQ值明显高于3.5 mm种植体(P<0.05);种植体ISQ值与颌骨HU值呈正相关(r=0.439,P=0.000<0.05)。CBCT在即刻种植的牙槽骨吸收观察中有一定应用价值,种植体稳定性与种植区部位、颌骨HU值及种植体直径有一定关系。

Abstract: The purpose of this study was to observe alveolar bone resorption and implant stability after immediate implantation with cone beam CT (CBCT). A total of 330 implants were implanted in 200 patients who underwent implant repair in our hospital, the CBCT was used to measure the alveolus absorption of immediate implantation and the Hounsfield unit (HU) value of jaw bone in the planted area, the Qstell ISQ implant stability measurement instrument was used to measure the implant stability quotient (ISQ). Analysis of variance was used for the difference between groups, and Pearson correlation analysis was used for correlation. One year after the operation, the bone absorption of mandibular anterior teeth and mandibular posterior teeth were significantly less than that of maxillary anterior teeth and maxillary posterior teeth (P<0.05); 1 year after surgery, there was no significant difference in PES score of maxillary anterior teeth, maxillary posterior teeth, mandibular anterior teeth and mandibular posterior teeth (P>0.05). The HU values of mandibular anterior teeth and mandibular posterior teeth were (79.20±8.02) and (78.43±9.11), respectively, which were significantly higher than that of maxillary anterior teeth and maxillary posterior teeth (P<0.05). The ISQ values of the implants with diameters of 4.3 mm and 5.0 mm were significantly higher than that of the implants with diameters of 3.5 mm (P<0.05). The ISQ value of implant was positively correlated with the HU value of jaw bone (r=0.439, P=0.000< 0.05). CBCT has certain application value in the observation of alveolar bone absorption after immediate 362 implantation, and the stability of the implant is related to the planting area, the HU value of jaw bone and the implant diameter.
